Lungfish evidence to "evolution"

This article was about the African Lungfish. This creature with thin arms and an eel like body would seem to be an example of the evolutionary track. This creature uses its arms to do walking like movements. The recent study done at the University of Chicago revealed that the African lungfish can use its thin pelvic limbs to not only lift its body off the bottom surface but also propel itself forward. Both abilities were previously thought to originate in early tetrapods, the limbed original land-dwellers. Lungfish also demonstrated both "bounding" motions, where both limbs moved at once, and "walking," marked by alternating limbs. Coupled with the ability of the lungfish to fully rotate the limb and place each subsequent footfall in front of the joint, the motion suggests that similar creatures would have been capable of producing some of the fossil tracks credited to tetrapods.
